new and useful Improvement in VVindow- Operators; and I do herebydeclare the folaccompanying taken in connection with the drawings andthe characters of reference marked thereon, to be a full, clear, andexact description of the-same, and which said drawings constitute partof this application, and represent, in-

This invention relates to an improvement in window operators, andparticularly to means for operatin ".he windows of vehicle doors.

- height In the more general arrangement of windows a lon strap isattached to the bottom of the sash y which the, sash may be raised; -andunless the sash is raised to the full and so that the lower edge can hemoved forward to rest upon the sill, means mustbe provided for holdingthe strap, and in many cases difficulty is experienced in raising thesash by a strap.

The object of this invention is to provide means forr'aising the sash bythe turning of a knob or handle; and the invention consists inthe'coiis'truction hereinafter described and particularly recited in theclaims.

In illustrating my invention 1 have shown the lower' part. of a'vehicledoor which may be ofany approved design, provided on op- Iposite sldeswith grooved guides S, 4, in

which the window 5 is guided for movethe sprocket vertical movement intothe lower part or pocket of the door. This window may have the usualwood or metal frame inclosing a glass, but as herem shown the glass isnot inclosed by a frame but is provided at its lower edge with a metalflange 6 the upper edge of the outer face of which is turned overforming a hook 7, adapted to engage with the upper edge of what I term afence 8 projecting upward from the sill 9. Connected with the flange 6and extending downward therefrom is an arm 10 to which one end of asprocket chain 11 is attached. This chain extends over a sprocket wheel12, and its other end connected with a cord 13 which passes around anidler pulley 14 at the bottom rail 15 of the door, thence upward throughan eye 16 at one side of the arm 10 over an I idler pulley 17 in linewith the sprocket wheel 12; down around a pulley 18 on a lever 19 andupward to the mid-frame 20v 'where it is'firmly secured. On the cord 13and secured by a pin &0 is a stop 21 which connects the cord to the arm10 as it is drawn down, but permits the cord to move slightly upwardwithout moving the arm and allows for taking up any slackness in thecord. The lever 19 is pivotally connected with a bracket 29. at one sideof the door and connected with the lever and with the bottom rail 15 isa spring 23 the tendency of which is to pull the lever downward, andhence counterbalance to a certain extent the weight of the window 5.

in a casing 25 secured to the mid-frame 20. Extending through the hub isa shaft 26 to the outer end of-which a knob or handle 27 is secured. Atits inner end the shaft is formed with radial lugs 28 setting intorecesses 29 in the inner face of the sprocket wheel12. The recesses arewider than the lugs so that a certain amount of independent movement ispermitted before the shaft will wheel. hub is a ratchet 30 havingdouble-face teeth 31 and connected with a D shape portion 32 of theshaft is a pawl tripper 33 adapted when turned to lift either of thepawls 34., 35, mounted 9n the cylindricalportion 36 of the casing 25 torespectively engage opposite faces of the teeth 31. Set into the outerend of casing 25 is a retainingplate 37 to this plate is and secured Thesprocket wheel 12 is secured to a sprocket wheel hub 24 mounted Rivetedto the.

the cylindrical portion 86 of the a spring friction yoke 38, the 1-10fingers of which embrace a. bushing 39 mounted on the D shape portion 32of the shaft and adapted to turn therewith. The

function of the lugs 28 and recesses 29 is to permit the shaft to have aslight movement independent of the ratchet-wheel to allow the tripper todisengage one of the pawls from the ratchet.

Whenthe sash is in the raised position as shown in Figs. 9 and 10 of thedrawings, the lower edge will be engaged with the fence 8 or the loweredge may rest upon the sill 9 in the usual way. In either event it willbe necessary to slightly raise the sash so as to release the lower edgeand bring it into alinement with the guides 3 and 4. Downward movement,however, will be stopped by the engagement of the pawl 3a with theratchet 30; but if the handle be turned to the left, the tripper 33 willlift the "pawl 34 out of the path of the teeth on theratchet as seen inFig. 7 due to the fact that the tripper may have a slight movementindependent of the ratchet owing to the provision of the wider recess29, it being understood thatthe number of teeth on the trippercorrespond to the numberof teeth on the ratchet; thus permitting thewmdow to be lowered byturning the handle, the spring 23 normally tendingto pull the lever -19 downward so that the slack on the cord 13 will betaken-up. "The moment, however, the handle is released, the ratchet willbe caught by the pawls 34 and 35 and further movement arrested. On theother hand, when the sash. is down, it may be raised by turning thehandle to the right, .and in this movement the tripper will raise thepawl 35 so that the ratchet will freely pass the pawl 35. The sash willbe locked at all points against movement other than that imparted byturning the handle, and the extent of.

movement of the lever is only half that of the window. Instead of usinga sprocket wheel and chain, the cord 13 maypass over .a grooved pulley41 mounted in thesame way as the sprocket. wheel 12 and the idlers l4and 17 may also be omitted as shown in 9.and1 50 In a window operator,the combination; with a vehicle door having a pocket and e mid-frame, awindow adapted to be moved up and down in said door, a wheel mountedwith the window, and a balancing lever mou ed in the pocket below saidwindow and ngagingwwith said HQXiOlG COBHGCtIOH.
